Abstract During the last few years, a radical restructuring of global optical networks supporting e-Science projects has caused a paradigm shift in computational science and collaboration technologies. From a scalable tiled display wall in a researcher's campus laboratory, one can experience global Telepresence, augmented by minimized latency to remote global data repositories, scientific instruments, and computational resources. Calit2 is using its two campuses at UCSD and UCI to prototype the research campus of the future by deploying campus-scale Green research cyberinfrastructure, providing on-ramps to the National LambdaRail and the Global Integrated Lambda Facility. I will describe how this user configurable "OptIPuter" global platform opens new frontiers in many disciplines of science, such as interactive environmental observatories, climate change simulations, brain imaging, and marine microbial metagenomics, as well as in collaborative work environments, digital cinema, and visual cultural analytics. Specifically, I will discuss how PNNL and UCSD could set up an OptIPuter collaboratory to support their new joint Aerosol Chemistry and Climate Institute (ACCI)..
